Why Choose Global Energy Insulation for Cavity Wall Insulation in Ferndale & Rhondda Cynon Taf?

Why choose professional cavity insulation for your Torfaen property?

Many older homes in Blaenavon were constructed with cavities that remain uninsulated, acting as a bridge for cold air to enter your living space. By choosing our PAS 2030 accredited installation services, you can achieve a substantial heat loss reduction and prevent the damp and condensation issues that often lead to black mould. Whether you own a semi-detached, terraced, or detached home, our insulation treatments are designed to improve your EPC rating and ensure your property meets modern MEES compliance standards for rental efficiency.

The Global Energy Insulation commitment to quality

We pride ourselves on being more than just installers. We are PAS 2035 retrofit specialists who look at your property as a whole system. This rigorous approach ensures that every installation is safe, effective, and compliant with current building regulations. Furthermore, because we understand that energy upgrades often require internal finishing work, our sister company, Global Plastering, is on hand to provide traditional, high-quality plastering services. This partnership allows us to offer a seamless, end-to-end service for every project we undertake in Torfaen.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited cavity wall insulation, reducing heat loss, and lowering winter energy bills in South Wales and South West England, Rhondda Cynon Taf, and across South Wales.

How do I know if my home in Ferndale has cavity walls?

+

Generally, houses built after the 1920s have a cavity—a gap between two layers of brick. You can usually tell by the brick pattern; if all the bricks look the same length, it’s likely a cavity wall. If some bricks look shorter (the ends of the bricks), it is probably a solid wall. We can confirm this for you with a quick survey.

Will cavity wall insulation cause damp?

+

When installed correctly by a PAS 2030 accredited professional, it actually helps prevent damp by reducing condensation on cold walls. We always check for existing issues and ensure your home has the right ventilation before we start.

How much money can I save on my bills?

+

According to the Energy Saving Trust, the average semi-detached house can save significantly on heating costs every single year. Given the current energy prices in the UK, the insulation often pays for itself in just a few years.
